Core Skill Set
AI & Multi-Agent Systems
Agent Orchestration
- ▹Multi-agent AI councils coordinated by a deterministic orchestrator
- ▹Typed agent contracts, domain routing, and conflict resolution
- ▹Model-agnostic provider abstraction, swappable as new models ship
Applied ML / LLM Integration
- ▹Use-case-specific prompt engineering and semantic pipelines
- ▹Document parsing, structured extraction, and multimodal inputs
- ▹Reproducible inference: deterministic policy layers over probabilistic agents
Creative AI
- ▹AI chatbots, document analyzers, and content generators
- ▹Dynamic document generation and layout parsing
Privacy & Compliance Engineering
PHI De-Identification
- ▹Identity stripped at ingestion, before any model ever sees the data
- ▹Layered detection: deterministic rules + the user's own profile, plus language-aware detection of names and identifiers in free text
- ▹Privacy treated as a measured metric and regression-gated on every code change
Compliance Controls
- ▹HIPAA / GDPR-style posture: encryption in transit & at rest, RLS, append-only audit logs
- ▹Zero-retention model APIs; no training on user data
- ▹BAA / DPA posture with every processor
Residency & Data Quality
- ▹In-region deployment: data residency as a deploy choice, not a rewrite
- ▹Quality gating: validated measurements only, never invented, always provenance-tagged
Security & Cryptography
Applied Cryptography
- ▹Non-custodial key management & device-bound encryption
- ▹Cross-chain signing and recovery flows kept fully client-side
- ▹Open-core cryptographic core, published under AGPL
Auth & Access
- ▹SIWE-style signature sign-in with rotating httpOnly sessions
- ▹Row Level Security (RLS) and least-privilege data boundaries
- ▹Separation of access, identity, ownership, and recovery
Hardening
- ▹API security, rate limiting, and abuse-resistant routes
- ▹Audit / provenance trails on every state transition
Security Auditing & Review
- ▹Autonomous, invariant-directed AI audit pipeline: invariant-by-invariant review of critical code
- ▹Cross-ecosystem coverage: EVM, Solana, Move, Cosmos, Substrate, Bitcoin, ZK circuits, and web2 access-control
- ▹Detection-only, human-triaged review against 100+ vulnerability classes, never exploits
Blockchain / Crypto
Industry Experience
- ▹9 years of crypto experience
- ▹Community Management & Developer Relations
- ▹Wore every hat: product, QA, support, and marketing
- ▹Built and ran blockchain platforms end to end
On-Chain Governance
- ▹Production Enjin OpenGov client: conviction voting, treasury proposals, live RPC + archive reads
- ▹EGOV1 on-chain metadata standard (content-addressed proposal backlinks)
- ▹Multi-wallet: WalletConnect v2 + Polkadot.js / Talisman / SubWallet / PolkaGate
Non-Custodial Infrastructure
- ▹Single-link receive across BTC / ETH / SOL / USDC
- ▹Device-bound key encryption, recovery flows, open-core crypto under AGPL
- ▹Custom token gating, credit systems, usage metering
Data & Systems Architecture
Event-Sourced Systems
- ▹Append-only, immutable event logs as the source of truth
- ▹Canonical data layers that normalise messy vendor payloads
- ▹State as a fold over history: answer "what changed and why" at any point
Human-in-the-Loop
- ▹Review / approval gates before any autonomous action
- ▹Provenance-tagged data with traceable, causally-linked outcomes
Technical Architecture
Full-Stack Development
- ▹TypeScript, JavaScript, Python
- ▹Next.js (serverless-ready), React
- ▹REST APIs, Webhooks, GraphQL
Distributed Systems & Cloud
- ▹Distributed systems, system & software architecture
- ▹Cloud application & database development
- ▹Real-time indexing and event-driven pipelines
Polyglot Services
- ▹TypeScript / Next.js product surface; Python for data & ML services
- ▹Small, independent, containerised services that ship and scale separately
Reliability & Scale
- ▹Batch processing, retry logic, idempotent real-time transaction handling
- ▹Rate-limit-aware CDN caching with graceful fallbacks
- ▹High-throughput operations in production (150,000+ on-chain ops)
Automation & Data Engineering
Internal Tools & Automation
- ▹Internal tools and automation systems for a healthcare provider
- ▹Operational dashboards, financial projections, and reporting
Data Analysis
- ▹Parsing, analyzing, and tagging transactions into structured pipelines
- ▹Forecasting fixed costs from historical patterns
Quantitative Logic
- ▹Custom technical indicators and model prototypes
- ▹Token-based access systems and tiered pricing mechanics
Product Thinking & Automation
